The woman reported Oct. 16 that Helmer had been harassing her after she ended their six-year relationship two weeks earlier, according to an arrest-warrant affidavit.

Two days later, she called Cedar Hill police again after she said Helmer got into her house through a garage window and went into her bedroom, the affidavit says. Police gave Helmer a criminal-trespass warning.

The affidavit says Helmer approached the woman and her children at a doughnut shop Nov. 3, the newspaper reported. He left when she told him to go, but she reported that he appeared at her home several minutes later and blocked her vehicle in the driveway.
